Specification of Letters Patent.-

Application med February 23, 1918. Serial No. 218,807.

To all whom it may concern Be it known that I, 'WILLLAM E. MUNS- Low, a citizen of the United States, residing at 246 North lth street, Steubenville, in the county of Jefferson and State of Ohio, have invented new and useful Improvements in Railroad-Ties, of which the following is a specification.

This invention relates to metallic railway ties and has for its primary object to produce a hollow tie which shall be of a simple, comparatively cheap but strong construction providing an ample support for the rails and being sufliciently resilient to permit of a desired yielding between the ties and rails when the weight of the rolling stock passes thereon.

It is a further object of the invention to produce a metallic tie" having means whereby rails may be readily secured thereon and which is integrally formed with means coengaging with the road bed for holding the same against longitudinal, lateral, or sinking movement. 7

It is a still further object of the invention to produce a hollow metallic tie which may be constructed of two sections, whereby the same may be easily cast or otherwise formed, readily handled, and easily and quickly associated, and also whereby the said sections may be electrically insulated from each other. 7

Other objects and advantages will appear as the nature of the invention is better understood, reference bein had to the accompanying drawings, in w ich,

Figure l is a side elevation of a tie constructed in accordance with this invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is a sectlo-nal view, upon a greatly enlarged scale, and approximately on the line 3-3 of Fig. 2.

Fig. 4 is a greatly enlarged sectional view approximately on the line 4-4 of Fig. 1.

Fig. 5 is a View looking toward the inner end of one of the sections comprising the tie.

Fig. 6 is a side elevation of a modified form of the tie.

Fi 7 is a sectional view approximately on the line 7-7 of Fig. 6.

Fig. 8 is a sectional view approximately on the line 8-8 of Fig. 6.

Fig. 9 is a side elevation of a further modification.

Fig. 10 is a sectional view approximately on the line 10-10 of Fig. 9.

Fig'. 11 is a detail 1011 itudinal sectional View approximately on he line 11-11 of Fig, 10; y

2 is a transverse sectional view approxlmatelyon the line 12-12 of Fig.2. In all of the for'r'ns of' invention the tie 15 cast, gnoided or otherwise formed tof pro: videa hollow body havin a flat base and its sides and top rounded i rom the base.

In Figs. 1 to 5 of the drawings the tick) comprises two connected sections, of similar construction, indicated by the numerals 1616. While in the remaining fig ties of the drawings the tie is illustrate as single element, it is to be understood that if desired such forms may be made in two sections.

In the said Figs. 1 to 5 the flat base of the tie is indicated by the numerals 17,,the rounded sides by the numerals 18, and the rounded top by the numerals 19.

Of course, the base, sides and topare integrally forrr'ied, and i face of each of the ties at a suitable distance inward of the ends thereof is disposed to provide a flat rail seat20. Th seat 20, adjacent the shoulders 21 providing the end walls thereof have suitable openings 22 through which are passed suitable elements designed for securin the rails on the'tie'.

The sections 16', a the inner ends thereof are forhr'ed each with an outwaidly extend ing flange 23. The flange is c'otitiflfiotis', that is, is formed with the base, the sides and the top of the sections, an conforms in snaps to the shape of the said base, sides and top. The flange, at the base portion of the section is therefore straight and provides what may be termed a transverse rib which, when the sections are connected and the tie arranged on the road bed, will enter said road bed and hold the tie against longitudinal movement. The flat base 17 holds the tie from sinking. When the tie is employed upon electric railways it is necessary to insulate the connected sections from each other, and therefore, between the flanges of the said section I arrange fiber washers 24 having openings alining with openings in the flanges 23. Through these alining openings are arranged fiber bushings 25, the same having one end provided with a flange 26. Through the bore of the bushings are inserted the shanks of bolts 27, the said bolts being engaged by nuts 28. By reference to the drawings it will be noted that the sleeve portions of the bushings 25 are longer than the top or upper sur- 2 tarmac the combined thicknesses of the flal es and the washer 24, and that the outer en of the said bushing is beveled, as at 29. Arranged between the nut 28 and the flange of the section adjacent to the said nut is an additional fiber washer 30. This washer has one of its faces provided with a continuous beveled portion 31 surrounding the opening therein through which the shank of the bolt passes, and this beveled portion is designed to c0ntact with the beveled end of the bushing 25, as clearly illustrated by the drawings. The head of the nut 27, will contact with the flange 26 of the bushing 25, and the nut 28 will contact with the Washer 30. The washers and bushings are, of course, con structed of insulatin material, and so it will be noted that whi e the sections comprising the tie are effectively connected the said sections are properly insulated from each other.

In Figs. 6 to 8 the body of the tie 32 is formed as previously described, but, as previously stated, I have illustrated this form of the invention as a single element. The flat base or bottom 33 of the hollow tie, during the process of manufacture is provided with transverse depressions 34 forming the said base or bottom with transverse ribs 35. It will be noted that the outer ribs 35 are at a suitable distance inward of the rail seats 36, so that the ribs are arranged at the center of the tie body. By this arrangement the outer ends of the tie are permltted a comparatively free movement in a vertical direction by the road bed, no ribs being provided outward of the rail seats 36. The ends of the ties may be compressed a ainst the road bed by the weight of the r0 ling stock passing thereover, thus yielding to the weight of the said rolling stock, but return- Oopien of this patent may be obtained for Me cents each, by addressing the "Commissioner of Patents, i

ing to normal position after the rolling stock has passed by. In addition to this the natural resiliency of the tie permits of the desired yieldahility between the rails and the tie, so that breakage of either the rails or the tie by the sharp impact of force incident to the weight of the rolling stock will. be thus obviated.

In Figs. 9 to 12 the tie 37 is substantially similar to that just described, but in the process of manufacture the flat base 38, inward of the rail seats 39 is depressed from the inner face of the base providing the outer face with transverse connected ribs 40.

It is believed, from the foregoing description, the simplicity and advantages of the construction will be apparent without further detailed description.

What I claim is:

A hollow metal tie comprising similar tions shaped to provide a flat base, rounded sides and top, said top, adjacent the ends of the tie having depressions forming rail seats, the confronting ends of the sections being integrally formed with outstanding flanges conforming to the cross sectional shape of the tie, said flanges having alining openin s, a fiber washer between the sections, anged fiber bushing passing through the openings in the flanges and opening in the washer, the sleeve portion of the bushing extendin beyond one of the flanges and having its e ge provided with a continuous bevel, a second washer having its central opening beveled to engage with the beveled end of the said bushin nuts screwed on the bolts and contacting wlth the last mentioned washer.

In testimony whereof I afiix my signature.
